We will explain how it helps improve mobile signal strength, and show types of mobile signal booster available so you can make an informed decision.

A mobile signal booster is a repeater system that involves the amplifier to enhance the mobile signal reception in various directions. The work of an outside antenna is to receive a signal from a mobile phone tower and send it to amplifier which enhances the power of that signal many times and sends it to the internal antennae which then transmits that signal into a building.

The main aim of the mobile signal booster is taking the existing cell phone signal around your car, office, workstation or home and amplifying it. After amplification, the signal is rebroadcasted to the area with no reception or weak signal.

Other optional components include the Attenuator which reduces unwanted frequency signals, Lightning Surge Protector, Splitter, and Tap.

How do Mobile Signal Boosters work?

A mobile signal booster has three main components i.e., external antenna, repeater, and internal antenna. The external antenna receives the cellular network signal from the cellular tower and transfers it to the repeater also called an amplifier, then amplifier amplifies the signal and sends it to the internal antenna which then broadcasts the signal in the weak signal area and users enjoy uninterrupted data and voice quality from the mobile phones. This is how all signal boosters work on all technology platform networks including GSM, CDMA, TDMA, EVDO, UMTS, HSPA+, and the latest LTE

The diverse obstructions affect the strength of the mobile phone signal. This includes natural obstructions like trees, construction materials in buildings and hills as well as the distance from the cellular tower. This is where the mobile signal booster system comes in. It simply enhances the strength of the cellular signal and broadcasts high-quality voice and internet data for the users.
